FIGURE 8.

Schematic model of the localization of NdhO in NDH-1M complex. The electron transport route is shown in red. Electrons originating from unknown donor (question mark) are transferred via the chain of Fe-S clusters N6a, N6b and N2 (dark red-yellow spheres) in NdhI and NdhK. NdhO may be located between NdhI and NdhK and restrict the efficiency of electron transfer from N6b in NdhI to N2 in NdhK and destabilize the NDH-1M complex.
